Engineered in compliance with DIN8077/DIN8078 standards using advanced computer automatic tooling.
As modern manufacturing demands transition towards extreme strength-to-weight ratios, Structural Reaction Injection Molding (SRIM) has emerged as the premier manufacturing pathway for heavy-duty composite components. Under the stewardship of Ehao Plastic Group, a high-tech private enterprise, we have successfully integrated advanced thermoplastic manufacturing with high-strength thermosetting molding systems.
By leveraging technology partnerships with the prestigious Chinese Academy of Sciences and Zhejiang University, Ehao group bridges the gap between traditional injection molding and structural composite engineering. Our industrial manufacturing lines feature advanced computerized automatic injection molding machinery sourced from Germany, ensuring sub-millimeter precision for complex geometries and critical load-bearing applications.
A high-level overview of the polymer engineering mechanisms that make SRIM the gold standard for structural composites.
Unlike standard injection molding which requires pressures up to 200 MPa, SRIM uses low-viscosity liquid monomers mixed impingement-style and injected at pressures below 10 MPa. This reduces tool wear and allows for massive, complex part molding without capital-intensive high-clamp tooling.
Prior to liquid polymer injection, a custom-designed continuous fiber preform (glass, carbon, or aramid) is placed in the mold cavity. The reactive liquid resin saturates this matrix completely, yielding unmatched flexural modulus and tensile strength properties.
As the reactive liquids meet inside the cavity, an exothermic cross-linking reaction creates a solid thermoset matrix within seconds. This rapid cycle time sets SRIM apart from traditional resin transfer molding (RTM) processes.
Global procurement teams in Automotive, Aerospace, Industrial Fluid Systems, and Heavy Equipment face persistent demands for light-weight components that do not sacrifice durability. Ehao Plastic Group satisfies this market gap by manufacturing ultra-durable structural injection components that stand up to corrosive chemical environments, high temperatures, and extreme structural loads.
With an extensive distribution footprint covering Europe, the Americas, and Southeast Asia, we maintain a robust supply chain configuration capable of rapid customization and direct-to-port delivery. Our logistics teams coordinate custom clearance paperwork, compliance verification, and standardized packaging designs to guarantee seamless integration with your production lines.
From high-performance domestic plumbing systems to massive structural agricultural and civil construction grids.
Ehao Group maintains a zero-defect ethos. We subject our raw polymer blends, continuous glass fiber mat preforms, and finished SRIM molds to a comprehensive 26-step scientific testing regimen. This system checks for cross-linking density, fiber volume fractions, mechanical load capacities, thermal resistance levels, and micro-void configurations.
Our quality control center works in direct synchronization with national laboratories. Every single batch of products must pass stress-rupture, pressure-durability, and dimensional tolerance checks to ensure compliance with the strict standards set by ISO 9001 and international DIN criteria.
